Large yellow croaker feed additive with intestinal tract protection effect and preparation method and application thereof

Abstract

The invention discloses a large yellow croaker feed additive with an intestinal tract protection effect and a preparation method and application of the large yellow croaker feed additive. The large yellow croaker feed additive is characterized by consisting of the following raw materials in parts by weight: 18-25 parts of rosemary oil, 16-26 parts of peppermint oil, 15-20 parts of citrus oil, 20-30 parts of calcium alginate, 10-20 parts of arginine and 5-10 parts of glutamine. The preparation method comprises the following steps: uniformly mixing the rosemary oil, peppermint oil, citrus oil, calcium alginate, arginine and glutamine according to the weight parts, and performing spray drying. The large yellow croaker feed additive has the advantages that the addition mass of the large yellow croaker feed additive in the feed is only 0.07-0.12 percent, villus in the intestinal tract of the large yellow croaker can be prevented from being damaged by antinutritional factors in a plant protein source, growth of the large yellow croaker is obviously promoted, the weight gain rate can be improved by 8 percent, the daily ration is improved by over 10 percent, and the protein digestibility is improved by 13 percent.

Description

technical field [0001] The invention relates to a feed additive for large yellow croaker, in particular to a feed additive for large yellow croaker with intestinal protection function, a preparation method and application thereof. [0002] Background technique [0003] Large yellow croaker is one of the traditional "Four Seafoods" in my country. It is very popular because of its fresh and tender meat. According to statistics, the total output of large yellow croaker in the country is about 180,000 tons, of which the output of artificial breeding exceeds 100,000 tons. With the development of the economy, people's demand for large yellow croaker is increasing day by day, so the production of artificially farmed large yellow croaker will continue to increase. [0004] At present, large yellow croaker farming mostly uses biological bait such as chilled miscellaneous fish, shrimp, and crab as feed, but because biological bait is difficult to store, easily deteriorates, and easi...

AI Technical Summary

Problems solved by technology

Therefore, in large yellow croaker culture, it will be the general trend to replace biological bait with artificial feed, but plant protein in artificial feed will cause the fluff in the intestinal tract of fish body to fall off, reduce the nutrient absorption rate and other problems, for this reason, it is necessary to develop a kind of food with Large yellow croaker feed additive with intestinal protection function
